Street-light cable tracing:
• Connect red clip to the incoming live cable
• Connect black clip to the lighting column if metal or to an independent ground point.
The live cable connector can be used in a similar way to apply
a signal directly to cables through live Low Voltage (LV)
isolators, such as fuse boxes in industrial sites.
LOCATING TIPS

Induction
If several conductors are running parallel and it is not possible to connect a transmitter, each line may be
located separately. Proceed as follows:
• Perform a sweep of the area to find the position and number of conductors in the area
• Map the direction in which the conductors are going
To trace the lines:
• Select induction mode on the transmitter
• Select the same frequency as on the receiver
• Place the transmitter on its side and in line with a conductor
• Ensure the conductor is directly below the transmitter
• This will null the signal directly below the transmitter and,
in addition, enable the other conductors to be located
• Locate each conductor and mark its position
• Move the transmitter down the route and continue
locating and marking
• Trace each conductor out of the search area
until the target line can be accurately located.
